The present invention relates to a 3D printer for manufacturing clothes, and more particularly, to a 3D printer for manufacturing clothes that can implement forward and backward movement of a needle for manufacturing clothes together with an existing carriage and a novel driving structure.

In general, in order to manufacture clothing, it is manufactured using a knitting machine such as a flat knitting machine. The flat knitting machine knits the fabric with the pattern entered into the program while the carriage moves left and right to the upper part of the wire needle in which a plurality of needles are arranged and supplies the thread to the needle. Looking at the driving principle of the conventional flat knitting machine, a formed butt is formed on the needle of the line needle, and a track corresponding to the above-described butt is formed on the rear side of the carriage, so that when the carriage reciprocates, the butt moves along the track. As a whole, knitting is made by moving the needle forward or backward.

However, since the knitting machine according to the prior art has to move the needle part forward and backward while reciprocating both ends of the needle part on which the carriage is arranged, there has been a problem in that it cannot be implemented when only a specific needle part needs to be moved forward and backward.

A driving force may be transmitted to the unit 10 .

The first moving part 4 is provided to move the first driving module 2 in a direction that approaches or moves the sun needle module 1 away from it. That is, when the wire needle part 10 of the wire needle module 1 is operated by the first drive module 2, the first moving part 4 moves the first drive module 2 toward the wire needle module 1 side. The first protrusion 13 of the wire needle 10 can be inserted into the track 21 formed in the carriage 20 of the first driving module 2 . Accordingly, as in the operation of a general flat knitting machine, the line needle unit 10 moves forward and backward according to the left and right movement of the carriage 20 . On the other hand, when the second drive module 3 is operating, in order to avoid interference, the first drive module 2 must be disconnected from the first protrusion 13, so that the first moving part 4 is connected to the first drive module ( By moving 2) away from the wire needle module (1), the coupling between the first driving module (2) and the wire needle module (1) is released.

The second moving part 5 is provided to move the second driving module 3 in a direction that approaches or moves away from the sun needle module 1 . That is, when the wire needle part 1 of the wire needle module 1 is operated by the second driving module 3, the second moving part 5 moves the second driving module 3 toward the wire needle module 1 side. The second protruding part 14 of the wire needle part 10 comes into contact with the connection part 30 of the second driving module 3 . Accordingly, the wire needle part 10 moves forward and backward by the operation of the connection part 30 . On the other hand, when the first driving module 2 is operating, in order to avoid interference, the second driving module 3 needs to be disconnected from the first protrusion 13, so that the second moving part 4 is connected to the second driving module ( By moving 3) away from the wire needle module (1), the coupling between the second driving module (2) and the wire needle module (1) is released.

On the other hand, the above-described second moving part 5 may be operated by a solenoid valve to move the above-described connection part 20 up and down individually. That is, since solenoid valves are individually connected to each connection part 20 , by moving the individual connection parts 20 up and down, the individual wire needle parts 20 can be moved forward and backward, respectively.

Accordingly, the first driving module 2 and the second driving module 3 are positioned on the upper side of the wire needle module 10 to correspond to the first and

second protrusions

13 and 14, respectively, and the first driving The first moving part 4 for moving the module 2 up and down and the second moving part 5 for moving the second driving module 3 up and down are respectively disposed.

From now on, the operation of the 3D printer for manufacturing clothes according to the present invention will be described.

8 and 9 are operational diagrams showing the operation of the 3D printer for manufacturing clothes according to the present invention.

As shown in the figure, in order for the first driving module 2 to move the wire needle part 10 forward and backward, it first approaches the wire needle module 1 side by the first moving part. Accordingly, the first protrusion 13 of the wire needle 10 can be inserted into the track 21 of the carriage 20 of the first driving module 2 . When the first driving module moves left and right while the first protrusion 13 is inserted into the track 21 , the wire needle 10 moves forward or backward toward the thread according to the shape of the track 21 . The operation of the wire needle unit 10 when moving forward or backward is the same as the operation of the wire needle unit of a general flat knitting machine. Accordingly, according to the shape of the track 21 , it is possible to manufacture clothes or the like having a desired shape. At this time, the second driving module 3 is maintained spaced apart from the

protrusions

13 and 14 of the wire needle 10 so as not to affect the operation of the first driving module 2 .

Next, the operation of the second driving module 3 will be described. In order for the second driving module 3 to operate, the second driving module 4 approaches the ship needle module 1 by the second moving part 5 . At this time, the first driving module 2 is kept spaced apart from the wire needle module 1 in order to avoid interference.

As the second driving module 3 approaches the wire needle module 1, the connection part 20 also moves to the wire needle part 10 side, and the wire needle part 10 is inserted into the groove of the thread 21 of the connection part 30. ) of the second protrusion 14 is inserted. Then, the driving unit 35 is operated to rotate the connecting unit 30, and the second protrusion 14 meshed with the screw thread 31 by the rotation of the connecting unit 30 moves forward, and the wire needle unit 10 is moving forward At this time, the number of rotations of the connection part 20 is sensed by the encoder 37 , and the forward distance of the wire needle unit 10 is adjusted according to the rotation speed of the connection part 20 .

When the wire needle part 10 advances to a predetermined position, the thread is caught on the needle nose 12 of the wire needle part 10, and when the driving part 35 rotates in the opposite direction again, the wire needle part 10 again rotates in the opposite direction. As it moves backward, the thread caught in the needle nose 12 also moves backward. By this driving mechanism, the wire needle unit 10 moves forward and backward to knit, and by the left and right reciprocating movements of the second driving module 3, clothes of a desired size or a desired shape are manufactured.

On the other hand, since the second moving part 5 can individually move the connecting part 30 up and down by the solenoid valve, it is possible to selectively move the wire needle part 10 forward or backward. That is, only the second support member 62 in which the solenoid valve operates among the second support members 62 of the support part 6 moves toward the wire needle part 10 by the individual operation of the solenoid valve. The connection part 30 supported by the second support member 62 moved by the operation of the second moving part 5 moves toward the wire needle 10 side, and the second support member 62 in which the solenoid valve does not operate. ), the connection part 30 does not move toward the wire needle part 10 and stays in place. Accordingly, the protrusion 13 of the wire needle 10 is inserted into the groove of the thread 31 of the selected connection part 30 . Then, the driving unit 30 is operated to rotate the connecting unit 20, and by the rotation of the selected connecting unit 30, the second protrusion 14 meshed with the screw thread 31 moves forward, and the selected wire needle unit ( 10) will only move forward or backward. In this way, instead of moving all the wire needles 10 forward or backward, only the selected wire needle 10 can be selectively moved forward or backward.

That is, in the case of the first driving module 2 , the first protrusion 13 is connected to the track 21 so that all the wire needles in the corresponding area along the track 21 move forward or backward, and the second driving module 3 ) can selectively move the wire needle 10 forward or backward, and control the forward/backward distance of the wire needle 10 by adjusting the rotation amount of the connecting part 20 . Therefore, in the case of the second driving module 3, it is possible to use it when printing a knitting structure of a special shape when manufacturing clothes.

The scope of the present invention is not limited to the above-described embodiments, but may be implemented in various types of embodiments within the scope of the appended claims. Without departing from the gist of the present invention claimed in the claims, it is considered to be within the scope of the description of the claims of the present invention to various extents that can be modified by any person skilled in the art to which the invention pertains.
